BATTERY HAND LAMP.

Application filed November 8, 1920, Serial No. 422,531.

To all whom it may concern: 1

Be it known that I, ERNEST ALsoHULEn, a citizen of the United States,and residing at New York, New York, have invented the new and usefulImprovement in Battery Hand Lamps, of which the following is aspecification.

This invention relates to battery hand lamps, and more particularly tomeans for locating a hand lamp in the dark.

It often happens that the user of a battery hand lamp may set the lampdown or drop it accidentally after extinguishing the light thereof, inwhich case, it may be difficult to relocate the lamp in the darkness. Itis convenient, therefore, to have means .on the lamp which will bevisible in the dark so as to indicate the location of the lamp. Suchmeans should, of course, be arranged to be visible from any directionwith respect to the lamp and in whatever position the lamp may happen tobe resting.

ne of the objects of this invention, therefore, is to provide means forvisually locating such a lamp from any direction and irrespective of aposition of the lamp.

' Further objects will appear from the following description taken inconnection with the accompanying drawing, in Which:

Figure 1 is a view in elevation of a lamp embodying this invention;

Figure 2 is a section on line 22 of Figure 1;

Figure 3 is a section on line 3-3 of Figure 2; and

"Figure 4 is a sectional view similar to Figure 3 but showing thisinvention applied to a lamp having a metallic casing.

Referring now to the drawing. Figure 1 represents a battery hand lamp ofthe usual construction having a casing 1 adapted to contain a batteryand a lamp, the circuit of which is controlled by a switch 2. Mounted onthe casing and uniformly spaced about the circumference thereof, arethree or more plugs 3, fixed to the casing by being forcibly insertedinto sockets or holes 4 therein.

Each plug 3 has a depression or cavity 5 punched or otherwise formedtherein. Within the cavity 5 is deposited a layer of luminous material6. Said luminous material may consist of any of the many well knownphosphorescent or luminescent materials and is preferably prepared bycoatmg a disc of paper therewith, which disc may then be inserted intothe cavity 5. The luminous material 6 may be provided with a transparentcover 7 made of transparent material such as celluloid or the like, andadapted to protect the luminous disc 6 from 1n ury or deterioration.After the insertion of the cover 7, the edges of the cavity 5 may beburred over to form a retaining flange 8 to retain the luminous materialand its cover 1n place. The plug 3, by being forced into the socket 4,is securely held in place.

WVhen the lamp is in the dark, the luminous material 6 will always bevisible by virtue of the light radiated therefrom. Smce there are threeor more plugs 3 spaced uniformly about the casing 1, one or more ofthese plugs will be visible in whatever position the lamp may assume. Itis, therefore, assured that the location of a lamp dropped or mislaidmay be determined from any direction and in any position of the lamp.

It is obvious that various changes may be made in the details ofconstruction Without departing from the spirit of this invention; it is,therefore to be understood that this invention is not to be limited tothe specific details shown and described.

Having thus described this invention, what is claimed is:

1. A battery hand lamp, comprising, a cylindrical battery-receivingcasing having a lamp, and a series of luminous elements spaced aroundsaid casing, substantially as and for the purpose set forth.

2. A battery hand lamp, comprising, a cylindrical battery-receivingcasing having a lamp, and a series of luminous elements spaced aroundsaid casing at oneend thereof, substantially as and for the purpose setforth.

3. A battery hand lamp, comprising, a cylindrical battery-receivingcasing having a lamp at one end thereof and a series of luminouselements spaced around said casing at the lamp end thereof.substantially as and for the purpose set forth.

In testimony whereof I afiix my signature this 21st day of Aug, 1920.

ERNEST ALSCER.
